Explain why voluntary transactions improve social welfare. What happens if transactions are forced? Can consumers get more or less happiness (holding their income/wealth constant) if they are forced intotransactions they don't want versus being able to choose what transactions they participate

Voluntary Transaction can be understood as: Voluntary transactions enhances social welfare by enabling suppliers and consumers to willingly participate in market transactions together.

When the transactions are forced, market transactions will reduce/decrease as a result of suppliers and consumers not being able to participate jointly willingly again.

This ultimately favors the consumers as they would gain more happiness if they would be be allowed to select what transactions they participate in.
